Problems solved by technology

[0002] At present, most of the traffic flow at intersections is realized through traffic lights. With the improvement of people's living standards, the number of vehicles is increasing, which brings traffic pressure to intersections. It is often necessary to wait for a long time at intersections during the peak period of vehicles. , brings inconvenience to people's travel, and because individual drivers have poor reaction, judgment ability and traffic awareness, they often run through red lights, which poses serious safety hazards. To solve the above problems, the invention patent No. 201110443530.X provides A continuous highway overpass structure is proposed. By setting the turning ramp, the vehicles with different steering directions will not interfere with each other, so that there will be no traffic lights at the intersection, the vehicles will be unimpeded, the road utilization rate will be improved, and the driving will be convenient and safe. Motor vehicle lanes and non-motor vehicle lanes are technically difficult and costly, and motor vehicles and non-motor vehicle shared lanes will inevitably interfere with each other, posing safety hazards. Therefore, it is impossible to realize the synchronous diversion of motor vehicles and non-motor vehicles
[0003] The invention patent with the patent number 201220481218.X provides a synchronous diversion intersection and T-shaped intersection road structure, which solves the above technical problems and realizes the synchronous diversion of motor vehicles and non-motor vehicles without traffic lights at intersections. The scheme realizes the left turn of the motor vehicle through the left turn bridge of the motor vehicle, and realizes the left turn and right turn of the non-motor vehicle through the circular lane of the non-motor vehicle, but due to the setting of the left-turn bridge, the non-motor vehicle lane of the transverse road must be lower than Motor vehicle lanes, which are easy to cause non-motor vehicle lanes to accumulate water in the rainy season, which is not conducive to the driving of non-motor vehicles; due to the small turning radius of the left-turn bridge, long and large vehicles cannot pass; the driving direction of the circular lane is clockwise , while the driving direction of the conventional round-the-island lane is counterclockwise, it is easy for the driver to make a mistake in judging the driving direction, causing the driver to drive in the opposite direction, and there are potential safety hazards

Embodiment 1

[0022] Embodiment one: refer to figure 1 with figure 2 As shown, there is no intersection point at the intersection of Chinese knot roads, including a longitudinal road A with a motor vehicle lane 11 and a non-motor vehicle lane 21, and a transverse road B with a motor vehicle lane 15 and a non-motor vehicle lane 25, and the longitudinal road A passes through a motor vehicle viaduct 13 and two non-motor vehicle viaducts 23 on both sides of the motor vehicle viaduct 13 span across the transverse road B, and four right-turn bridges 12 extending to the right relative to straight vehicles are erected between the longitudinal motor vehicle lane 11 and the transverse motor vehicle lane 15. The viaduct 13 top is erected with the annular left-turning bridge 14 that is respectively connected with four right-turning bridges 12, and the deck width of the right-turning bridge 12 and the annular left-turning bridge 14 joints is approximately equal to the width of the right-turning bridge ...

Embodiment 2

[0026] Embodiment two: refer to image 3 with Figure 4 As shown, the lane layout of motor vehicles is the same as that of embodiment one, and the main difference is: the lane layout of non-motor vehicles turning left and right is different. There is a circular lane 26 that surrounds the exit / entrance of the non-motor vehicle viaduct 23 and is connected with the exit / entrance. The circular lane 26 is connected with the longitudinal non-motor vehicle lane 21 and the transverse non-motor vehicle lane 25 respectively. The left and right turns do not interfere with each other, and the specific method is: when the non-motor vehicle gets on the non-motor vehicle viaduct 23, it is to go straight or to realize the left turn through the circular lane 26 after crossing the bridge. When the non-motor vehicle needs to turn right, it needs to Enter the circular driveway 26 to the left before the non-motor vehicle viaduct 23 and enter the rightward transverse non-motor vehicle lane 25 alon...

Abstract

The invention discloses a non-cross connection point of crossroad of Chinese knot road. The connection point comprises a longitudinal road and a horizontal road, which are respectively equipped with motor vehicle lanes and non-motor vehicle lanes; the longitudinal road spans the horizontal road through a motor vehicle viaduct and two non-motor vehicle viaducts located at two sides of the motor vehicle viaduct; four right-turn bridges which stretch towards right corresponding to the straight vehicles are set up between the longitudinal motor vehicle lanes and the horizontal motor vehicle lanes; circular left-turn curved bridges which are respectively connected with four right-turn bridges are set up above the motor vehicle viaduct; four left-turn lanes which are connected with the horizontal non-motor vehicle lanes and does not affect the straight vehicles are arranged on the longitudinal non-motor vehicle lanes; four right-turn lanes which stretch towards right corresponding to the straight vehicles are set up between the longitudinal non-motor vehicle lanes and the horizontal non-motor vehicle lanes. The road structure provided by the invention can separate the motor vehicles from the non-motor vehicles synchronously without traffic light, thus, the non-cross connection point improves driving efficiency and safety, and overcomes many problems of the synchronous bypass road structure in prior art.
